so we can say we are a lot better in terms of actually passing tests :-)

That is a piglit run from two AMD drivers a year apart.

but really its only Intel working a lot on core mesa at the moment, with others expending time as jobs allow. Its not as is Red Hat can ship GL3.0 drivers anyways so working on them isn't a great spend of our time. and working on GL doesn't get you CL or video decode or anything. Also it not as if Red Hat can ship video decoders, so again no reason for us to invest heavily in them.

Perhaps some of the distros that do ignore patents could invest more in these.

Why not? It would nice being able to play OilRush at the highest quality... but again performances are the main issue. Also we need at least 3.2 to get the best from wine.

Support in Mesa != Support in drivers. At the same time we need power management, performance, OCL, hw decoding, etc. etc. so I guess that only a little minority of us would really need OGL 4.x over all these feature.

PS. Sandy Bridge and Ivy Bridge only support OGL 3.x so I think that Intel isn't directly interested in supporting OGL 4.x.

True, what I expect from Red Hat or any other commercial distribution that is mostly popular on servers is to only care about OpenGL up to the level it can run a composited desktop with decent performance. What I would expect though is to care about power management, but probably what customers you have with AMD graphics cards have embedded graphics that don't use that much power to matter.

If a distribution makes money out of selling their product it will care about patents. If it doesn't make money it doesn't have what to invest, so if a mesa developer is also a Gentoo or Arch developer that would be a pure coincidence, and I don't know of other distros enabling patented code by default.
